VEHICLE-AXLE.

SPECIFICATION forming part of Ifetters Patent No. 524,903, dated August 21, 1894.

Applicationfiled December 26, 1893.

To all whom it may concern:

Be it known that I, WILLIAM L. MASSEN- GALE,.of Deatsville, in the county'of Elmore and State of Alabama, have invented a new and useful Improvement in VehicleAxles, of which the following is a full, clear, and exact description.

My invention relates to an improvement in vehicle axles, and it has for its object to so construct the spindles of an axle, that when the spindles are worn they may be restored to proper shape without the necessity of cutting the axle or reforging or reworking the spindle, and further to provide a means whereby the restoration of the axle may be accomplished by any person of ordinary intelligence.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of .reference indicate corresponding parts in both views. p

Figure 1 is a side view of a portion of an axle and one of the spindles thereof; and Fig. 2 is a section taken through the spindle trans versely and on the line 2-2 of Fig. 1.

In carrying out the invention the spindle A, is made in two sections, an upper section 10 and a lower section 11, the upper section being of greater thickness than the lower section in fact the division between the two sections is made below the central longitudinal line of the spindle, as is clearly shown in Fig. 1.

The body A of the axle of which the spindle forms a part is provided with a recess 12 at its end adjacent'to the spindle, and the horizontal or upper wall of the recess 12, is in a plane with the under surface of the upper section 10 of the spindle, the recess '12 being made to extend from side to side of the body of the axle, and the recess extends through to the under face of the axle, its inner or end wall being inclined downwardly and outwardly, as shown at 12 in Fig. 1.

The lower section 12 of the axle spindle is a counterpart in every way of the upper section 10, and said lower section is provided Serial No. 494,787. (No model.)

with a tongue 11, extending from its rear end and forming a continuation of the section; and the tongue 11, is made of such size and shape as to completely fill the recess 12 in the body of the axle, while the under face of the tongue 11 will form virtually a continuation of the under face of the uncut portion of the body of the axle. t

The outer end of each spindle. section. 10 and 11 is reduced and threaded, forming virtually a screw section 14 for the reception of theQa-xle nut. The two sections are held .to gether primarily through the medium of a dove-tail rib 15, formed centrallyupon the of the ends of the tongue 11, the axle re-' cess 12*, and the dove-tail rib 15 and its receiving groove 16, together with the character of the rib 15 and groove 16, will efiectually prevent one section from leaving the other,

and the lower section of the spindle is reinforced by its purchase upon the vbody of the axle.

In addition to the means above set forth for holding the two sections of the spindle in re movable engagement, other means are used upon the body of the axle, consisting of clips B, one of which is placed upon the body of the axle near the inner end of the spindle, the said clip likewise embracing the tongue of the lower spindle section, as shown in Fig. 1,

and a second clip is placed upon the axle where the tongue of the lower spindle section engages with the inner wall of the axle recess 12.

It is well known that the under surface of the axle spindle is the only surface which is worn through the action of the wheel; therefore, when this surface becomes worn to too great an extent and an axle is constructed as above set forth, the lower section 11 of the spindle need simply be removed and'a new IOO The spindle being in two parts, friction will be materially lessened, and it is-obvious that the detachable section of the spindle only will become hot, the fixed portion remaining'cool;

therefore, this portion will not easily spring.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1'. An axle spindle, comprising an upper and lower section, one section being provided with a central longitudinal dove tail rib and the other with'a dove-tail groove to receive the said rib, substantially as described.

2. In an axle, a spindle constructed in two sections, one section being provided with a dove-tail rib and'the other with a'dove-tail grooveto receive the rib, the lower section be ing provided likewise with atongue adapted to enter a recess'in 'the body of the axle, and

clips locking the tongue to'th'e axle body, as

and'for'the purpose set forth.

3; The combinatiomwithan axle, of a spindle con'structedin" two sections, one section being provided with a dove-tail groove'a'nd the other with a dove-tail rib to enter the groove, the upper section forming an integral portion of the axle, the axle being provided with a recess in its under face, and a tongue integral with the under section of the spindle, shaped to fit into the axle recess, and clips bindingthe tongue to the axle body, as and for the purpose set forth. I

4. The combination, with an axle body provided with a recess in its under surface at its spindle end, the end wall of the recess being -inclined,of a spindle constructed in two sec- ,tions, the upper section being integral with the axle body, andj*its under surface being flush with the upper wall of the axle recess, the said upper section being also provided with adove-tail groove-theinner-end of which is beveled, adove-t'ail rib formed upon thelower section of, the spindle, adapted to enter the dove-tail groove, aitongueconstituting an integral portionofthe lower spindle section and fitted to enter the axle recess, and clips engaging with the-bodyofthe-a-xleand with said-tongue, substantially asset forth.
